手動式高度充氣擴肺術是運用時間常數及吸氣時間原理令肺泡回復。實際作法是醫護人員將甦醒球連接在病人的氣切口或氣管內管的接口上，然後用兩手慢速擠壓甦醒球，緩慢的吸氣速度及中期暫止，再將甦醒球快速的放開。此操作方式是允許足夠的時間使狹窄氣道及低順應性肺區的肺泡平衡充氣，使肺泡再度膨脹，如此則使吸入氣體於整個肺有更好的分佈。手動式高度充氣擴肺術可以有效幫助患者肺泡回復，呈現痰液清除、通氣量改善、肺塌陷的部份擴張、順應性改善、動脈氧合增加和呼吸功減少。本文介紹手動式高度充氣擴肺術。

　　　　　Manual hyperinflation is a medical practice intended to restore pulmonary vesicles by applying time constants and the principle of inspiration terms. In practice the medical professional first links the resuscitation bag to the patient's intubation or tracheostomy, then squeezes the resuscitation bag, using both hands, in a slow motion to provide a slow inspiration speed, accompanied by mid-term intermissions, after which the resuscitation bag is suddenly released. The rationale of this practice is to allow sufficient time for the narrow breath path and the alveoli of low compliance aptitude in the pulmonary area to inflate in a balanced manner, so that the pulmonary alveoli may recruit again, so that eventually the air being taken in with the inspiration gains better distribution in the entire lung. Manual hyperinflation helps alveolar recruitment, which results in secretion clearance, ventilation improvement, lung collapse prevention, lung collapse re-inflation, dynamic compliance improvement, artery oxygenation improvement and work of breathing reduction according to certain clinical reports from foreign sources. This article introduces the manual hyperinflation technique.
